In the third quarter of 2025, the galvanized steel wire welded mesh industry is undergoing an unprecedented structural transformation under the dual impetus of rigid policy constraints and technological innovation breakthroughs. Hot-dip galvanizing has completely replaced cold galvanizing as the mainstream in the market. Green production and precise customization have become the core competition tracks for enterprises, and the industry concentration continues to increase.
The intensive efforts at the policy level have become the "baton" guiding the industry's transformation. After the implementation of new regulations such as the "Technical Guidelines for Construction Quality of 'Good Houses'" and the "Measures for the Administration of Pollution from Livestock and Poultry Breeding", the performance requirements for galvanized mesh in the fields of building crack prevention and breeding anti-corrosion have significantly increased. Data from a residential project in Zibo, Shandong Province, shows that the wall cracking rate of the section using ordinary cold-galvanized mesh reached 12%, and the rework loss exceeded 800,000 yuan. The cracking rate of the adjacent sections using hot-dip galvanized mesh was only 0.3%, successfully passing the 70-year durability design acceptance. Under the pressure of policies, the market penetration rate of hot-dip galvanized steel wire mesh has soared from 45% in 2024 to 68%. The 3,000-mu "vegetable basket" project in Luancheng, Shijiazhuang, has even listed it as a mandatory material.
Technological innovation is reshaping the industry landscape, and three major process changes are accelerating market reshuffling. Green production has become a hard constraint. The national energy efficiency benchmark requires that the energy consumption per unit of hot-dip galvanizing be reduced to below 300kgce/t. The traditional pickling process is accelerating its exit due to pollution issues, and the orders of enterprises without pickling technology have increased by more than 40%. In the construction field, it is clearly stipulated that the zinc coating thickness of hot-dip galvanized mesh sheets should be ≥80μm and pass the 1000-hour salt spray test. For aquaculture scenarios, it is mandatory that the corrosion resistance of the fences be over 8 years. Leading enterprises such as Sishun have achieved a 28% reduction in carbon emissions per ton of steel through pickle-free production lines. The 85μm zinc coating thickness has stably met the new regulations in both fields. The market share of their products in the construction and breeding segments has both exceeded 62%.
Full-scenario customized services have become the key for enterprises to break through. In response to the demand for crack prevention in residential buildings, the enterprise has launched a special mesh with a 12.7×12.7mm mesh size and an 85μm zinc coating. A dual protection scheme of 3×3cm precise mesh and chromium-free passivation was designed for large-scale chicken farms, reducing the escape rate of chicks to 0.1%. The zinc-aluminum alloy coated mesh customized for the Southwest Bridge ensures no corrosion for two years in a high-humidity environment. These customized products not only meet policy requirements but also bring significant economic value - the initial investment in hot-dip galvanized mesh is 30% higher, but it does not require rework for 10 years, and the comprehensive return exceeds 2.8 times.
Industry data shows that the domestic demand for hot-dip galvanized welded wire mesh will exceed 950,000 tons in 2025, with a compound annual growth rate of 6.2%. The current industry has entered an era driven by both policy adaptation and green production. Enterprises with acid-free washing processes, intelligent quality control systems, and full-scenario service capabilities are seizing the initiative. For the purchasers, checking the zinc coating test report, verifying the production process qualifications, and obtaining actual application cases have become key means to avoid market chaos. This industry upgrade centered on quality and environmental protection is laying a solid material foundation for infrastructure construction and the development of modern agriculture.
